Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed Apri125, 1918. Serial No. 230,632.

To all whom it may concern:

Be it known that we, SANDOR LASZLO and BENJAMIN KOVAOS, a citizen of the United States, and a subject of the King of Hungary, respectively, residing in New York, in the county and State of New York, have invented certain new and useful Improvements in Antislipping Devices for Heels, of which the following is a specification.

Our invention relates to anti slipping devices to be worn on the heel of a shoe and has for its object to provide a plurality of pointed members or calks on the surface of said devices whereby the gripping action is provided to prevent slipping. A further object of our invention is to provide a device of the above mentioned character which can be applied to the heel and disconnected from same in an easy and quick way.

A still further object of our invention is to provide a device of the above mentioned character, which is simple as to its construction and cheap to manufacture and therefore more commercially desirable than the anti slipping devices at present in use.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists of certain novel features of construction, combinations and arrangement of parts as will be hereinafter fully described and claimed.

For a complete understanding of our invention reference is to be had to the following description and accompanying drawings in which Figure 1 is a bottom elevational view. Fig. 2 is a sectional view on the line 2-2 of Fig. 1. Fig. 3 an elevational top view of the device. Fig. 4: an elevational view of the upper surface of the lower plate of the device, and Fig. upper plate of same, and Fig. 5 an elevational View of the leather heel piece to be applied between the two plates of the device.

Referring more closely to the drawings, numeral 1 represents a metal plate, preferably of steel, which is to be secured to the heel of the shoe by set screws 2. The middle part of the upper surface of this plate, that is, of the one in contact with the heel, is recessed as at 3, while a raised strip 4:, is left around the edge upon which the plate rests on the heel. Near the center part of plate 1, are two raised bosses 5, specially formed and applied to a correspondingly 6 an elevational top view of the cut opening 6. Above same there is another speclally formed hole 7, cut in plate 1. On the lower surface of plate 1, we secure with the same screws 2, a leather heel-piece 8 shown 1n Fig. 5, which has an opening 9, cut in such a way as to clear both openings 6 and 7 of plate 1.

When the anti slipping device is not in use and the elfective part of it disconnected, as when indoors, the parts of the device as yet described remain on the heel, being permanently attached to it by screws 2, but the wearer walks on the leather heel piece 8 which hides the metal plate 1 of the device and permits noiseless and elastic walking.

l/Vhen it is desired to attach the effective parts of the anti slipping device to the heel, the disconnectible bottom plate 10, which can be carried in the wearers pocket or in any suitable place, comes into play.

Said plate 10 has a spring 11, applied to its bottom surface by non rotatable pin 12, which goes through said plate and has a round washer 18 fixed non rotatably at its other end, projecting through to the top surface of plate 10 and having a narrower neck portion 12 between washer 13 and plate 10. This washer is pushed through hole 7 of plate 1, said hole 7 being somewhat larger in diameter, whereupon it is pushed backward, mentioned neck portion entering slot 14 and washer 13 remaining on the top surface of plate 1, thereby binding same with plate 10.

Another device is applied to lower end of spring 11 to fix detachable plate 10 rigidly 1n alinement with permanent plate 1. The lower end of spring 11 carries a rotatable pin 15 with a knob 16 above the spring and a specially formed cross piece 17 at the other end of pin 15. When plate 10 is detached, spring 11 pulls pin 15 upward and cross piece 17 is drawn into the correspondingly formed opening 18 of plate 10 and is flush with its surface.

When plate 10 already has been attached to permanent plate 1 by washer 13 as described above, the final adjustment and fixing of same is effected the following way: The lower end of spring 11 is pressed down by knob 16 and cross piece 17 pushed through openings 18 and 6 of plates 10 and 1 respectively. When cross piece 17 isentirely beyond the upper surface of stationary plate 1, in recess 3 and in a horizontal position between bosses 5, with a quarter of a revolution it is turned into perpendicular position to the preceding one, as in Fig. 3, thereby lying against the two other sides of bosses 5 and across opening 6 which position keeps it locked.

When desired to detach plate 10, knob 16 is turned backward till cross piece 17 strikes against the bosses 5, in which position spring 11 pulls it through opening 6 of plate 1, into opening 18 of plate 10, and plate 10 can be pulled downward till washer 13comes into alinement with the hole 7 and plate -10 lifted out of contact with plate 1.

To the "bottom surface of our device We apply a plurality of small spiked points 19,

preferably screwed into the bottom plate as shown in the drawings, and having a square portion on their head by which they may be unscrewed and replaced when worn. These spikes enable the wearer to get a firm and secure grip on the ground on which he Walks no matter What the condition of the surface of same may be.

The form of our invention, illustrated in the drawings and referred to in the above description, is the preferred embodiment of our invention and we found it most efficient and practical. Yet as the conditions concurrent with the adoption of our device will necessarily vary, we desire to emphasize the fact that various minor changes in details of construction and arrangement of parts may be resorted to when required, without sacrificing any of the advantages of Dill: invention, as defined in the appended c aim.

Having thus described our invention, what we claim as'new is:

In an anti-slipping device for shoe heels, a metal plate permanently applied to said heel, a recessed portion in the upper surface of said permanent plate, a leather heel-piece coverin said permanent plate, a detachable metal pdate a crosspiece applied to said detachable plate in such a Way as to automatior calks on the lower surface of said detachable plate, substantially as and for the purpose set forth.
